61902-2RS1/W64 Bearing Product Overview & Core Advantages
The 61902-2RS1/W64 is a single row deep groove ball bearing designed for exceptional performance in compact spaces. This metric precision bearing features an integral Solid Oil lubrication system and sealed construction, making it a highly reliable, maintenance-free solution. Its optimized design delivers smooth operation and long service life, ideal for applications demanding high reliability and consistent performance under radial loads.
61902-2RS1/W64 Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Advantage |
|---|---|---|
| 2RS1 | Contact seals on both sides | Provides excellent protection against contamination and retains lubrication effectively. |
| W64 | Solid Oil lubrication | Ensures a consistent, reliable lubricant supply, enabling maintenance-free operation and suitability for a wide temperature range. |
61902-2RS1/W64 Bearing Structural Features & Performance Benefits
- Robust Sealed Construction: The 2RS1 contact seals on both sides effectively shield the bearing interior from dust, moisture, and other contaminants, significantly enhancing operational reliability and service life in harsh environments.
- Maintenance-Free Operation with Solid Oil: The W64 suffix indicates the bearing is filled with a polymer-based Solid Oil that replaces traditional grease. This eliminates leakage, reduces friction, and provides a consistent lubricating film, making the bearing ideal for applications where re-lubrication is difficult or undesirable.
- High Precision and Smooth Running: Manufactured to ABEC 1 | ISO P0 tolerance class with CN radial internal clearance, this bearing ensures low noise and vibration levels, contributing to smooth and precise rotation.
- Compact and Lightweight Design: With a 15 mm bore, 28 mm outside diameter, and a narrow 7 mm width, this bearing is engineered for space-constrained applications without compromising on load capacity.
61902-2RS1/W64 Bearing Typical Application Areas
- Small Electric Motors and Gear Motors
- Office Automation Equipment (e.g., Printers, Scanners)
- Medical Devices and Instrumentation
- Cooling Fans and Blowers
- Precision Spindles in Low to Moderate Speed Applications
- Food and Beverage Processing Machinery (where maintenance-free operation is critical)
